OIL-WELL REGULATOR.

Application filed July 20,

This invention relates to regulators for oil wells or the ,like and has particular reference to improvements for such regulators as that set forth in my co-pending application for Letters Patent filed' in the United States Patent Office on June 23, 1925, and given Serial Number 39,152.

The primary object of the present invention is to set forth improvements and refinements of construction which have'not heretofore been known or used in the manufacture of oil well regulators.

The present invention relates particularly to means for extinguishing a burningoil well without losing the siphoning effect or pressure of the same.

A further object of this invention is to provide a novel flow-restricting member which has desirable operating means adapted. to be controlled from a point some distance from the well.

Minor objects will be apparent throughout the detailed specification and claim.

In the drawing,

Figure 1 is a side elevation of the oil well regulator constructed in accordance with the present invention.

Fig. 2 is an end view of the same.

Fig. 3 is a-vertical central section of the device taken on line III.III of Fig. 2.

Fig. 4 is a cross section of the regulator taken on. line IVIV of Fig. 3 with the slidably mounted shaft in a position to turn the flow of oil or gas through the passage formed for that purpose, and,

Fig. 5 is a perspective view of the slidably mounted shaft removed from its working position. I

Like reference numerals refer to like parts throughout the several views, and the numeral 6 designates the well-known oil or gas well casing through which the oil or gas is allowed to escape.

It is known that oiD or gas escaping from the well will oftentimes becomes ignited and create a heat intense enough to preclude its being turned ofi by anyone close to the mouth of the well. D

Thisregulator which is interposed in casing 6 to control the flow of oil or gas or entirely cut off the same may be constructed to provide a body composed of an upper and a lower member 7 and 8, respectively, which should be of heavy metal and screwthreaded to casing 6 as shown in Figs. 3 and 4. An

opening 9, formed by members 7 and 8 al- 1925. Serial No. 44,806.

lows unrestricted flow of the oil or gas as long as there is no need or desire to stop the same ordireet the flow to one side through passage 10. When this action becomes necessary, shaft 11, which also has an opening 12 therethrough to continue opening 9, may be I moved along until opening 9 is entirely closed. A further movement. in the direction of the arrow (Fig. 3) will cause angled connecting passage 13'to join opening 9 and passage 10. This action, when caused to take place when oil or gas is burning at the upper end of casing 6 will extinguish the flame and still allow the well to retain its siphoning action by permitting the oil or gas to pass out passage 10 immediately after the fire is extinguished.

Any suitable clamps 14 may be used to anchor the regulator to casing 6 and to the ground, and a flange l5integral with one end of member 11 may be used torlimit the movement of the same.

Novel means for operating the shaft 11 from a great and safe distance may be made as shown in the drawing, which consistsof providing a pair of arms 16, fastened as at 17 to the upper block 7 of the regulator body. Arms 16 support a bearing 18 which holds a screwthre'aded stub shaft 19 adapted to engage tapped cavity 20 of member 11.

The outer end of shaft 19 is provided with A regulator of the class described comprising' in combination, a body including an upper and a lower member, an arcuate groove formed in the adjoining face of each of said members whereby an opening is formed through said body from one end to the other, a single horizontal passage formed by a coacting lateral groove in each member of said body, a shaft having a head formed on one end thereof, mounted in said opening through said body and having one of its ends projecting .0

tappe socket in the projected end of said beyond the end thereof, the axial shaft, a screw supported for rotary move whereby when said screw is operated to pull me-nt only by the body to engage said tapped the shaft laterally, flow of fluid through said socket, vertical passages through each of said vertical passageis diverted to flow horizontal- 10 body members adapted to aline with a verti- 1y through said lateral passage.

5 cal passage extending through said shaft In testimony whereof I hereunto afiix my when said regulator is in the open position, I signature this 15th day of July, 1925. and an angular passage formed in said shaft, MALVA M. ROBERTSON.
